How can I tell if a given git tag is annotated or lightweight?
提问by G. Sylvie Davies
I type git tagand it lists my current tags:
我输入git tag并列出我当前的标签：
1.2.3
1.2.4
How can I determine which of these is annotated, and which is lightweight?
我如何确定哪些是注释的，哪些是轻量级的？

git for-each-reftells you what each ref is to by default, its id and its type. To restrict it to just tags, do git for-each-ref refs/tags.
git for-each-ref告诉你每个 ref 默认是什么，它的 id 和它的类型。要将其限制为仅标签，请执行git for-each-ref refs/tags.
[T]he output has three fields: The hash of an object, the type of the object, and the name in refs/tags that refers to the object. A so-called "lightweight" tag is a name in refs/tags that refers to a
commitobject. An "annotated" tag is a name in refs/tags that refers to atagobject.- Solomon Slow(in the comments)
[T]he 输出具有三个字段：对象的哈希值、对象的类型以及引用该对象的 refs/tags 中的名称。所谓的“轻量级”标签是 refs/tags 中引用
commit对象的名称。“带注释的”标签是 refs/tags 中引用tag对象的名称。-所罗门慢（在评论中）

The git show-ref -d --tagscommand sort of does it, since lightweight tags occur once in the output, and annotated tags occur twice. Also, only annotated tags include the "^{}" dereference operator in the output.
该git show-ref -d --tags命令是这样做的，因为轻量标签在输出中出现一次，而带注释的标签出现两次。此外，只有带注释的标签在输出中包含“^{}”取消引用运算符。

7fe2caaed1b02bb6dae0305c5c0f2592e7080a7a refs/tags/1.2.4
588e9261795ec6dda4bd0a881cf1a86848e3d975 refs/tags/1.2.4^{}
And that output can than be massaged with the unix sort, sed, cut, and uniq commands to make the output more readable:
然后可以使用 unix sort、sed、cut 和 uniq 命令处理该输出，以使输出更具可读性：
git show-ref -d --tags |
cut -b 42- | # to remove the commit-id
sort |
sed 's/\^{}//' | # remove ^{} markings
uniq -c | # count identical lines
sed 's/2\ refs\/tags\// a /' | # 2 identicals = annotated
sed 's/1\ refs\/tags\//lw /'
For my original repo (from my question) it outputs this:
对于我的原始回购（来自我的问题），它输出以下内容：
lw 1.2.3
a 1.2.4
(e.g., 1.2.3 was "lightweight" and "1.2.4" was annotated).
（例如，1.2.3 是“轻量级”，而“1.2.4”被注释）。
回答by Noufal Ibrahim
Get the tag name (say foo) and then do a git cat-file -t foo. If it's an an annotated tag, cat-filewill tell you that it's a "tag". If it's a simple tag, cat-filewill tell you that it's a "commit".
获取标签名称（例如foo），然后执行git cat-file -t foo. 如果它是一个带注释的标签，cat-file会告诉你它是一个“标签”。如果它是一个简单的标签，它cat-file会告诉你这是一个“提交”。
Update: As oxymoron said in his comment, git showworks too but it gives you more information than just what kind of tag it is.
更新：正如矛盾修辞法在他的评论中所说，git show它也有效，但它为您提供的信息不仅仅是它是什么类型的标签。

Please try using git describe
请尝试使用 git describe

By default (without --all or --tags) git describe only shows annotated tags.
默认情况下（没有 --all 或 --tags） git describe 只显示带注释的标签。
